问题如下:
A portfolio has a return history of 100 weeks.The lowest six week returns are shown in the table. Using the hybrid approach, the 5% VaR is close to?
选项:
A.4.55%.
B.4.24%.
C.5.61%.
D.5.91%.
解释:
C is correct.
考点:Nonparametric Methods
解析:第五个最低收益率的累积权重是5.33 %.
5% VaR是发生在第4个最低收益率与第5个收益率之间。采用线性插值法进行计算:
5% VaR=6% - (6%-5.5%) ×(5%-3.8%)/ (5.33%-3.8%)=5.61%
百分之5的var不是第五损失么
